Answer:

<em>The speed of the water bottle at impact with the street is 49 m/s</em>

Explanation:

<u>Free Fall Motion </u>

A free-falling object falls under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. Free-falling objects do not experience air resistance.

If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is g = 9.8 m/s^2.

The final velocity of a free-falling object after a time t is given by:

vf=g.t

The water bottle dropped by Jamie takes t=5 seconds to impact the ground, thus its speed at that moment is:

vf= 9.8*5

vf =  49 m/s

The speed of the water bottle at impact with the street is 49 m/s

Suppose you have a toy car made of copper. The car has the mass of 224 grams. What is the volume of your toy car?
melamori03 [73]

Answer:

Volume = 25 cm^3

Explanation:

We know that the density of any kind of substance or material is equal to:

density= mass/volume\\\\densitycopper= 8.96gram/cm^3\\mass=224grams\\volume=mass/density\\\\volume=224/8.96 = 25 cm^3

Superconducting materials generate a strong ______ field. gravitational pressure magnetic nuclear
lisov135 [29]
Superconducting materials don't generate anything. 
But since their electrical resistance is zero, it's possible
to push a huge current through them without loss, and it's
the huge current that sets up a strong magnetic field around
the conductor.

A 0.25-kg ball attached to a string is rotating in a horizontal circle of radius 0.5m. Assume the tension force is directed hori
borishaifa [10]

Answer:

T= 19.74 N

Explanation:

The tension in the string will be equal to centripetal force on the ball. (Newton's 3rd law, equal acting and reacting forces acts on a body)

T = Fc

Fc = m w ²r

here:

m = 0.25 kg, r = 0.5 m

w = 2 rps = 2 * 2π rad/s      ( ∴ 1 revolution = 2π radians )

w = 4π rad/s

Fc = m w ²r = 0.25 * ( 4π )² * 0.5 N

Fc = T = 19.74 N

T= 19.74 N
